Redesign event loops to be thread-safe and deterministic
The new event loop design has a single event queue that is
synchronized to protect against data races.
The removal of events in the queue by EventOwner is
deterministic.
Test-Information:
All unit and integration tests with TSAN and
cxxflags=-DBOOST_SP_USE_PTHREADS on Debian 8.2 pass without
reports.
Multiple Swiften/QA/ClientTest/ClientTest runs under
different CPU stress caused no TSAN reports on Debian 8.2.
Swift itself only causes TSAN reports related to Qt itself,
out of our control, and most likely false positives, i.e.
TSAN not detecting the synchronization method inside Qt
correctly.
Unit tests pass without errors and successfully connected
to Slimber on OS X 10.10.5.
